TO ALL WHOM 1T MAY CONCERN:

Be it known that I, CALEB CADWELL, of Waukegan, in the county of Lake, and in `the State of Illinois, have invented an Improved Harvester; and I do hereby declare that the following is a full and exact description thereof, reference being had .tor the accompanying drawings, and to the letters of reference marked thereon, making a. part of this specification, in which- Figure 1 is a plan view of my invention.

Figure 2, a sectional elevation of the'same, taken through the line X X, fig. 1.' v

Figure 3, a transverse sectional elevation of the motion-wheel, sbbwing the motion-lever, side-piece, and strap, also the double joint, arranged to operate in combination with the motion-lever and pitman. i

The nature of my invention consists- First, in the use of a double lever attached to 'the tongue of the harvester', and arranged with one or more notches, fitted to rest on the main shaft of the'drive-wheelsfor the purpose of regulating the position of the cutter-bar when in use, or moving from place to place. I

`Second, in arranging a eam-wheel to work vin anoscillating-frame, and to operate in combination with a jointed lever, for giving motion to the cutter-bar. l

Third, in the construction and arrangement of double joint for connecting the motion-lever tothe pitman, in order that the latter may work easily, yand not become entangled with grass and weeds.

Fourth, in the peculiar arrangement of levers, chains, and a catch, for regulating the inclination of the cutter-bar, and holdingit in position for use. I

In order to give a correct understanding of my invention, Ihave marked corresponding parts with similar letters, and will new give a detailed description. I

It will be seen from the drawingsthat the harvester is represented as complete, except the travelling-wheels and thc main drive-wheel, these parts being so well understood as to need no description.

A strong iron frame, A, is made to support the various parts of the harvester, and with a slot through it,l

for the purpose ot' placing an oscillating-frame, Q Q, figs. 1 and 3, in aconvenient position for supporting a cam-wheel, W, which gives motion to the cutter-bar U, iig. 1. And to accomplish this purpose, one end of the frame Q is. hung to a strap, z', lig. 3, by inean's of a joint, Z, the lower end of the strap being alsoarranged with a joint, l, and secured by a: pin iitted'in the frame A. The motion-lever R is hungto Vthe frame A, as seen at 13, tig. 2, and is jointed to the frame Q Q at Z', and is also attached to the pitman V by a doublejoint, '.l.-

This joint is formed by making an open mortise in the lower end'of the motion-lever for the Pitman-shank to pass through, and rounded at the sides of the mortise to fit the boxesg g, through which the pitman also passes, and is made to hold the joint together, by means of a nut and pin.

A bottom view of the doublejoint is clearly shown at iigure B B. Y,

The cam-wheel Wis fixed on a shaft, having bearings at both sides ofthe frame Q Q., and receives its motion by means ofa common drive-wheel, not shown, and a pinion, 20, which may be thrown `in and out oi' gear by a cam-lever, 2, as seen by the dotted llines 4, g. 1; 'i Y The arrangement for regulating the pitch of the. cutter-bar is as follows: A rod, C, is jointed to the shoe, B', and to a rod, D, and brace, G, the latter beingjointed to frame A. l

A lever, E, is jointed to rod D, frame A, and a notched catch, F, arranged to hold on to a pin, g, iig. 2, fixed to frame A.

This construction is simple, but convenient for raising the cutter-bar U, as the lever E is placed within reach ofthe driver's seat, and can be readily drawn back and forth.

An angle-brace, B, is hinged to frame A and finger-bar A', and has a lever, 21, jointed to it, and touthe' under side of frame A, and placed in a suitable position for lthe driver to raise it up and down when the outerend of the cutter-bnr isto be elevated, for passing over obstacles, Sie.

A chain, 1T, is attached to the nose of shoe B', and to the rod 22, to preventr the `linger-bar A from doubling under, and chain, 16, is secured to said shoe at the opposite end of the rod, for keeping the fingerbar at right angles with the tongue J. 4

A bail, L, is jointed to. frame'A at M M, by means of n. rod, 22, passing through said buil, and projections P P, and is made to pass through the tongue J, and is supported by bearings N N, made in a plato, K, figs. 1 and 2, fastened to the tongue, andmadc to project outward for that purpose, and the support of a caster\vhecl,I. A lever, a, is hinged to the tongue J, and has a chain, 23, attached to it and to the rod 2'2, and a catch, c, jointed to it, with one or more notches, c, for locking over the main shaft, f, oi` the travelling-wheels, as seen at g. 2.

The end of this lever is within reach ofthe drivers seat, and can be used to raise the .front of the harvester when passing to and from a field, when desired.l

The inner travelling-roller, 11, is hung to the inside of frame A by a. bolt, 12, and is used to prevent the harvester from dragging on 'the ground; and to prevent the` roller from elogging,'1 bevel its periphery, as seen at iig; 4.

A seat, 7, having a tool-box, G, is placed yat the rear ofthe harvester, and on springs, at the front ends of which are foot-pieces, 8, for the convenience ofthe driver.

Having thus fully described my device, what I claim, and desire to secure by Letters Patent, is 1. The double joint T, in combination with the moton-leverR and pitman Y, arranged to operate substantially as specified.

2. The combination of the oscillating-frame Q Q, cam-wheel W, strap z', motion-lever R, doublejoint 'Land pitman V,al1 arranged as and for the purpose herein specied.'

3. The lever a, attached to the tongue J, in combination with catch c, chain 23, nnrl roll 22, arranged to raise the front of the harvester, as described.

4. The arrangement of the rods C D, brace Gc, lever E, catch F, and shoe Bi', for raising the cutter-barl U, substantially as described. i Y
